SPECIFICATION forming part of Letters Patent No. 502,339, dated August 1, 189 3.

Application filed April 27, 1893. Serial No. 472,061- (No model.)

To @ZZ whom, it may concern:

Be it known that I, F. CORTEZ WILSON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Crimping-Tools; and I do hereby declare thatthefollowingis afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements` in sheet metal crimping tools of that class employed for crimping the edges of sheet metal caps upon the flanged mouthsof can spouts, and for other similar purposes.

The object of the invention is to providean improved construction in tools of the character referred to, and it consists in the matters hereinafter set forth and particularly pointed out in the appended claims. l

A crimping tool embodying my invention comprises in its construction a stock provided at its lower end with a part adapted to engage the upper surface of the sheet metal cap, and one or more crimping rolls revolubly supported, adjacent to the edge of said part, on the lower ends of downwardly projecting arms which are pivotally connected to the stock and are adapted to be oscillated to force the crimping rolls inward into position to bend or close the edge of the cap around or upon the ianged mouth of the can as the tool is rotated. In one approved form in which I have practically embodied my invention, said pi voted arms are adapted to be oscillated by direct pressure upon the tool along the axis thereof, the stock of the tool being to this end formed of two parts arranged to telescope together, or to otherwise slide longitudinally of each other, one part including a circular plate or disk which engages the upper surface of the cap and the other part includinga shank to which any suitable handle or other device for operating the crimping tool is attached. In such case the arms carrying the crimping rolls are pivoted to one part of the stock and are so connected or arranged with reference to the other parts that when said parts are forced together the lower ends of the arms will be swung inward, bringing the crimping rolls into position to crimp the edge of the cap, as hereinbefore stated. This will be more fully understood from the following description of a construction of crimping tool of the class last referred to, taken in connection with the accompanying drawings illustrative thereof, in which V Figure l is a partially sectional elevation of a crimping tool constructed in accordance with my invention, showing the same as first applied to a cap and can spout, with the crimping rolls out of operative position. Fig. 2 is a horizontal section of the same taken on line 2-2 of Figi. Fig. Sis adetail section, showing the position of the parts when the crimping rolls are in operative position. Fig. 4. is a sectional view showing the cap as first applied to the can spout; and Fig. 5 is a similar view after the cap has been subjected to the operation of the crimping tool.

A designates the stock of the tool thus illustrated and A the circular plate or disk, provided at the lower end of the stock and adapted to engage the upper surface of the sheet metal cap. As ordinarily constructed, such caps (designated Sin the drawings) are formed with a depressed center sof sufficient diameter to fit the interior of the mouth of the can spout S and center the cap relatively thereto, and in such cases said disk A', as herein shown, is provided on its lower surface with a central circular lug or annular rib c, adapted to fit within the recess s and center the tool relatively to the cap and can spout. Said disk is herein shown made separate from the body portion of the stock A and is connected thereto by means of a cylindric lug or spindle A2 provided centrally on the upper side of said disk and engaging a central longitudinal bore A3 in the stock A. A set screw a provided in the stock and projecting into a wide annular groove or recess c2 in the spindle A2 normally, prevents the withdrawal of the spindle from the bore A3, while at the same time permitting longitudinal and rotary movement of said spindle relatively to the stock. The latter is herein shown as provided at its lower ends with three radially projecting lugs A4, located symmetrically around the stock and formed at their outer ends with vertical slots or recesses of. Within said recesses are pivoted, upon horizontal pivot pins a4, the oscillatory arms or levers B, the downwardly projecting ends of which IOO support the crimping rolls C at points adjacent to the edge of the disk A. As herein shown said rolls are journaled upon the arms B in such manner as to be movable longitudinally thereof, and are inaintainedin substantially the same plane with said disk A by means of wide iiauges c provided on the uppei ends of the rolls and engaging au annular groove a5 in said disk A. The lower ends c of said crimping rolls O are also enlarged as shown so that when said rolls are thrown inward against the disk A said lower ends c project beneath the edge of said disk in such manner as to bend or crimp the edge of the sheet metal cap over the flangediiiouth of the can. v

The upper portions of the oscillating levers B are herein shown as bent radially inward through recesses a6 into the central bore A3 of the stock where they engage the upper end of the spindle A2. A suitable spring A5 provided in the upper end of said bore A3 serves to normally maintain said levers in contact with the upper end of the spindle A2 and to maintain the latter in its low ermost position relatively to the stock, and, in this instance, a washer a7 is shown as inserted between said spring and the inner ends of the levers B to afford a sufficient bearing surface between the same.

For the convenient manipulation of the tool, the stock A is herein shown as formed at its upper end with a tapered shank AG, to which any suitable handle A7 may be applied.

The construction of the tool being as described, the manner of operating the same is substantially as follows: A sheet metal cap S is laid over the mouth of a can spout S", and

the annular rib a of the crimping tool is inserted in the depressed center of the cap as shown in Fig. l. The stock A of thetool is then forced downward by pressure upon the handle A7, causing the spindle A2 to move upward relatively to said stock and thereby raise the inner ends of the bent levers B. Obviously such action throws the lower ends of said levers inward and forces the crimping rolls C mounted thereon toward the edge of the disk A. Such inward movement of the crimping rolls will obviously bend or crimp the adjacent'portion of the edge of the cap upon the flanged mouth of the can spout, and the tool being thereupon rotated such crimping action will be continued throughout the entire circumference of said cap. During such crimping action the disk A and the annular rib a at the lower side thereoii` will obviously act as an anvil to resist any distortion of the cap and spout by the pressure of.

the rolls and to afford a iirm backing between which and said rolls the edges of the cap and spout may be compressed. The upper end of the spindle A2 is preferably rounded off or chamtered and the engaging ends of the bent levers B made beveled as shown, so that said spindle exerts a wedging action as well as a direct thrust upon said levers and enables the tool to be operated with a less-pressure than would otherwise be required. Ob-

-vvously by the downward movement of the Stock A the lower ends of the arms B Will be forced downward past the disk A', but the rollers C will, by the engagement of tli'eir flanges c with the groove-A5ot` said disk, simply slide farther up on the arms B and thereby be maintained in their normal position relatively to said disk A. As soon as the pressure upon thehandle is released the spring A5 will lift the stock A to its uppermost position relatively to the disk and release the vrollers C from their engagement with the cap S. Y W Y n Y I claim as my inventionl. A tool for crimping caps upon can spouts comprising a stock made of two relatively movable sections, one adapted to be grasped in operating the tool and the other provided with a cap engaging part, a lever pivoted to one of the sections and adapted for oscillation by the relative movement of said sections, aud a crimping member upon the lever, substantially as described.
